48 people were shown 100 sets of numbers of different lengths, split up into a number of smaller chunks. After seeing each set, they were asked to recall the numbers in a memory test.
The results found that, on average, people were good at remembering about 7 numbers and 4 chunks before memory errors started kicking in.
Chunk for clarity.
Our short-term memory is limited, so whether you're designing a food menu or trying to share a new idea, prevent Analysis Paralysis by breaking information down into 3-5 smaller bites that are easier to process.
Chunk requests.
If you're asking for a lot of info from customers, how can you break the task into more manageable segments?
Data capture company, Typeform are a great example of this, turning the concept of chunking into a core USP for its data capture products.
Chunk for long-term understanding.
Boost knowledge retention by structuring each chunk learned to build upon what was learned in previous ones. Repeat past chunks to build a strong, modular connection between fragmented bouts of learning.
Language app, Duolingo does this in an engaging visual way.
47 subjects were given around 20 small, manual tasks to complete, one at a time. Experimenters randomly interrupted completion of half of these tasks. After, subjects were asked to recall as many tasks as possible.
There was a 90% higher recall of incomplete and interrupted tasks than those completed.
Make important task completion frictionless. If customers leave your site without finishing their order, make it effortlessly easy to get that completion feeling, such as allowing for completion with a single click, tap or swipe.
Focus on completion’s emotional release. Providing reward incentives for task completion actually demotivates consumers. Instead, remind them not just of the product they’ve not yet bought, but of the feelings that this ‘purchase task’ will unlock.
Make known campaigns incomplete and interactive. Greater familiarity with an advert increases consumer ability to complete an interrupted ad message. Active participation also boosts ad memory (Heller, 1956). So if your popular campaign’s reaching its end, consider a special second follow-up version that allows for active participation in completing the ad message.
40 students were taught a topic and either given the respective homework once instantly or 3 times over the next 3 weeks. They then had an exam a month later.
Those who had the homework spaced out over time performed much better in the exam than those who were asked to do it immediately after learning.
Spread out the learning.
Research shows that spaced repetition is the most robust means of learning but is rarely used by companies. Most knowledge is delivered once and forgotten, wasting money and time. Develop shorter learnings spread over time, using different tools, both digital and physical.
Use it or lose it.
Knowledge only sticks when we use it. After reading a book chapter, summarize learnings into bullet points, a list of actions, or even better, become the teacher. Blinkist could send some simple interactive questions after readers have finished a book. Use Slack app QuickQuiz to follow up Lunch & Learns with aTiny Habitof bite-size questions.
Make progress trackable.
Learnings apps like Duolingo and Memrise create powerful Feedback Loops through points systems, daily goals and leaderboards to create positive reinforcement. Tracking progress gives us a sense of growth and improvement.
